Clank Legacy has been an absolute blast for my wife and I (we each play two characters). I've been a big Penny Arcade fan for ages so the humor hits my sweet spot, and the legacy aspect of keeping the gameplay light and steadily adding a bit more complexity each round as you "earn" it was perfect for my wife who's a much more casual gamer.
I backed the 2nd season on kickstarter just recently and it looks like they're leaning even more into the story aspect of legacy gameplay so I'm hoping it still hits the right balance for us.
